Marc Goldberg, a respected dog trainer certified by the International Association of Canine Professionals (IACP-CDT), shares a unique approach to addressing crate anxiety in dogs. Initially inspired by a challenging situation with a Doberman showing distress in the crate, Goldberg experimented with various materials to create a comforting environment. The journey began with cardboard boxes and shredded newspapers, leading to an accidental discovery of the dog's nesting behavior as a calming mechanism.
